I couldn't be on a forum like this without passing this info on. Its SO simple yet i don't know how i survived without it.
Go to your App Market, search County (as in COUNT y? :) )
Download! Voila! Just tap your screen when u finish a row, or whatever way works for u to keep track of your rows. You ll never want to be without it again!
Just my 2 cents for now.
